Hi, I purchaseed an XDA flame on www.hi-mobile.net, on july. The display of this device not worked so their replaced it with new device. Yesterday I received it. I extract it from its box, I put sim card inside, I put battery inside and I connected it to AC power. Immediately the led become blink orange. I leave it to charge for 4 hour, then I remove it from AC power, I press on/off button but it not work, the screen remain black. I reconnect to AC power and led become orange, I press on/off button and it turned on but now the led turned off. After installation procedure, I see battery icon was with pressure point. I see in the panel where is write: "Main battery: Unknow" "Battery power remaning: Unknow". The I try to turn on the phone. In the wirless manager I tap on phone icon, but nothing happen. I try to tap on Phone menu and it write on screen "The wireless radio is not present". I see in the device information panel "GSM Version: P5C2", "IMEI: 353095010051772".
I'm disappointed of this device, and I want someone help me to solve this problem. Is not possible that I buy 2 device and 2 device not work!
What do I do??
Thanks, please answer as soon as possible.

So I've got a Sensation phone that won't start. Bootloader menu can't be accessed as well. When I plug it in, the orange LED lights up, stays on for about 3 seconds, then goes off for about a second and finally lights up again and stays on permanently. Tried with a different battery - no luck. When I connect it to the pc via micro usb cable, the computer recognizes the phone (installs drivers for htc sensation). And there's something more - when I connect the charger in a completely dark room, the display backlight becomes visible. The screen doesn't light up but it also doesn't remain completely dark. It's like the screen is on but completely black.
So what can I do? Thought that the power button might be defective, so I removed the black tape over the button and short circuited the two small pins on top of the button. It didn't work. I can't fire it up through abd, because usb debugging is off. So do I have any options beside selling it on ebay or giving to a service technician?

Thanks for the suggestion
I haven't tried this solution yet because the problem does't seem to be a QHSUSB_DLOAD issue.
Upon connection with pc it identifies with hardware id USB\VID_0BB4&PID_0FF9&REV_0228 as a mass storage device...
Hey guys, I have a problem with my TF700
First of all my TF700 is rooted, but I didn't change the ROM or any of those advanced stuff.
My TF700 has a black screen problem...When I hit the power button the screen comes on but its black...as in the light is on but its a dim black light, you can't see anything but I can tell the tablet is on. When I press the power button again the dim light comes off.
When I try pressing the power button and the volume down button or any of those combinations the tablet just vibrates and turns off and the dim light comes back on with no display. I don't see any of the things that usually comes on when you press those combinations in order to cold boot the device.
When I plug in the charger, the charger light is green indicating that it is fully charged.
When I plug it in to my computer it says installation of driver failed, and it says no APX driver found.
Can someone help me please?
Get a proper HDMI cable and connect it to your TV's HDMI port and see if that will at least let you see what's going on.
So the Xperia z3 will not start and it seems that it doesn`t charge, furhther it wont turn on.
Tried VOL+\- + Power button and the little button behind the SIM-Cover - no reaction
When I connect it with a (working) charging unit the LED will light up red and the display shows a battery-symbol filled red on the bottom (10%)for a few seconds, then it turns off and shows the same things (led and screeen). Well it is some kind of loop. I charged it for over 24 hours with different charging devices (up to >2A)
When I connect it to a PC the LED is dark blue. PC Companion says that the phone is locked and I schould unlock it, which is impossible as I am not able to turn the device on
Connecting it to the PC while holding the VOl- the PC Companion can do a software-repair and it says it works, but it doesn`t change the behavior of the phone.
I once got hands on an old Z3 wich showed the same behavior, it was just the battery. I changed the battery and it is now working fine again.
